Concept of brightness of bulb in a circuit

Answers

Answered by basavaraj5392

Answer:

The brightness of a lightbulb is given by its power. P = I2R, and so brightness depends on current and resistance. If the bulbs are identical, they have the same resistance. ... This, then, is a circuit problem even though you do not need to specify the values of the currents.
